What is fastText?
FastText: A word-embedding library that represents each word as the sum of vectors for its character n-grams. It can produce a vector for words never seen in training and copes well with spelling variants and rich word forms.
FastText: an example
FastText builds a vector for the unseen word "chaiwala" from pieces like "cha", "hai" and "iwa".
